I took some shots today at work of some of the beads the welders in my department lay down. The first six were done by a 5-year veteran welder with extensive certifications in MIG tank welding, the last two were done by a 30-yr veteran welder with extensive certifications in everything.
Any questions, feel free to ask.


321SS, TIG, .020"

321SS, TIG, .032"

1018 mild steel, MIG with TIG root pass, varying thicknesses

5052-T5 Aluminum, TIG, .125"
(This is one of the shittiest aluminums to weld. Extremely watery and unstable)

A36 mild steel, MIG, varying thicknesses up to 2"

A36 mild steel, MIG, varying thicknesses up to 2"

A36 mild steel, MIG, varying thicknesses from .188 to .500.

Top ring is Hastelloy X forging, bottom ring is Hastelloy X sheetmetal.
Weld wire is Hastelloy W, laid on a rotary positioner with continuous feed.
Basically this part is welded with the torch in one hand, the feeder in the
other, one foot on the positioner pedal, and one foot on the power pedal.

Hastelloy X casting in the middle of 2 sheetmetal rings, TIG, .090

 

Not too bad soem good welds going on there

Looks like the first pic of the 321 was rushed with alot of heat.

The rotary ones aren'y overly impressive for using a rotary type setup

Otherwise it looks good

Yeah craazy MIG btw

thats what i was thinkin..... i wish i could lay a bead of MIG that good

 

probably one of those new lincoln "STT" or whatever pulsewave type migs.

that first stainless weld is ~ guys dips are way too far apart. Thats what i call a "nascar" weld because the nascar boys all love the hugely spaced coins lol.

 

nice, i could barely see the difference w/ mig + tig on the beads

 

Actually it's with an old Miller running at ~17V and 121 IPM with .045 wire.
As for the first weld, it's a corner weld on a tank holding over a ton of water. He was looking for some serious strength in the joint.

The third weld has MIG on the left (in the arc), TIG on the right (the straight joint).

 

what the heck is this?

 

a box of the lightest rims eva, yo.

actually I have no idea- we just make the stuff. Nobody tells us what it does.

Some of those mig welds are super impressive....

 

that first pic with the tig pass looks like it was fusion welded. If we do a box or something with a small outside corner then its usually fusion welded (like less then 1/8" thick). Those mig passes look interesting, ut I question the need to have a coined look. is it simply for aesthetics or is that the way the machine functions? In between the separate "pools" the weld looks rushed.

 

No, it's just a standard TIG weld, wire and all.

The "coined look" is standard for welding, it's the welder's technique and has nothing to do with the machine. If you just moved the gun along with the trigger pulled, you'd end up with a tall skinny bead proportional to the wire diameter and rate at which you moved across the work piece (also with useless weak joint). There's no "rushing" to these welds, all are done with the utmost precision.
